Description
Technical Field
The invention relates to the technical field of cat litter, in particular to plant cat litter and a preparation process thereof.
Background
Before the advent of cat litter products, pets (such as cats) had to be discharged outdoors or on wood chips or sand, which caused significant environmental pollution. With the growing number of pet cats in the home, a litter product has emerged that can be used to absorb pet urine, fecal waste, and control odors.
Early cat litters were predominantly non-clumping clay litters, but because such litters did not clump, people were required to dispose of cat waste. With the continuous progress of cat litter technology, agglomerated clay litter and sodium-based bentonite litter appear, because the clay litter and the sodium-based bentonite litter can quickly wrap cat urine, so that the cat urine can form an agglomerate, the cleaning is convenient, and the generation of foul smell can be reduced.
Disclosure of Invention
The invention aims to provide plant cat litter and a preparation process thereof.
In order to achieve the purpose, the technical scheme adopted by the invention is as follows: a plant litter comprising a litter composition and a binder;
the cat litter composition comprises the following components in parts by weight: 20-40 parts of bentonite raw ore, 50-100 parts of starch, 10-20 parts of activated carbon, 5-20 parts of carrageenan and 5-10 parts of flavoring substances;
the mass ratio of the binder to the litter composition is 5-15%.
Preferably, the sweet potato starch is powder obtained by drying, compacting, grinding and filtering sweet potato residues.
Preferably, the plant litter comprises the litter composition and a binder;
the cat litter composition comprises the following components in parts by weight: 20 parts of bentonite raw ore, 50 parts of starch, 10 parts of activated carbon, 5 parts of carrageenan and 5 parts of flavoring;
preferably, the plant litter comprises the litter composition and a binder;
the cat litter composition comprises the following components in parts by weight: 30 parts of bentonite raw ore, 75 parts of starch, 15 parts of activated carbon, 15 parts of carrageenan and 7 parts of flavoring substances.
Preferably, the plant litter comprises the litter composition and a binder;
the cat litter composition comprises the following components in parts by weight: 40 parts of bentonite raw ore, 100 parts of starch, 20 parts of activated carbon, 20 parts of carrageenan and 10 parts of flavoring substances.
Preferably, the starch is sweet potato starch; the bentonite raw ore is prepared by airing high-quality bentonite raw ore, performing sodium modification in a factory and drying; the adhesive comprises polyurethane; the flavoring substance is concentrated lavender extractive solution.
A process for preparing any of the foregoing plant litters comprising: mixing the components of the cat litter composition, adding the adhesive in proportion, uniformly mixing to obtain a mixture, preparing the mixture into particles, and drying the particles to obtain the plant cat litter.
Preferably, a mixer is used to mix the components of the litter composition and to mix the litter composition and the binder.
Preferably, the particles have a particle size of 0.5-0.8 cm.
Preferably, the sweet potato residues are subjected to fermentation treatment before drying for 1-2 days, and then dried after the fermentation treatment.
Compared with the prior art, the invention has the advantages that:
strong deodorization: the odor in urine or excrement can be tightly absorbed and not diffused, so that the air in a room is kept fresh and free of odor;
instant moisture absorption: the pet urinal can quickly suck up urine and water in excrement discharged by pets in a very short time; the moisture absorption amount reaches more than 80 percent of the self weight and the appearance is still dry;
the price is low: the sweet potato residue is utilized and has low price, and the sweet potato residue is processed and refined to generate special yeast and enzyme which can decompose organic molecules causing odor in urine and feces, thereby destroying the generation of odor on the molecular structure. The yeast and enzyme have no special taste, can not be detected by human and cat, and perfectly realize biological deodorization. The deodorized cat litter can be used in the basin for a long time;
easy to handle: the plant cat litter is caked in capacity, does not leave marks, is low in dust, is light in specific gravity and small in garbage amount, and can be flushed in a toilet; the household use is convenient and safe.
